説明Validamycin A is produced by the fermentation of Streptomyces hygroscopicus var. limoneus nov. var (30). Structure revised (31). Colorless, odorless, hygroscopic powder. V.p. Negligible at room temperature. Solubility: Readily soluble in water, soluble in methanol, dimethylformamide and dimethyl sulfoxide. Slightly soluble in ethanol and acetone. Sparingly soluble in diethyl ether and ethyl acetate. pKa 6.0 Stability [α]24D + 110 (water).
使用Validamycin A is the major analogue of a family of cyclitol disaccharides isolated from Streptomyces hygroscopicus var. limoneus by researchers at Takeda in 1970. Although commonly regarded as an aminoglycoside, validamycin shares little in common with conventional aminoglycosides such as streptomycin and gentamicin. Validamycin A is a potent antifungal agent and is used to control fungi in crop production. Validamycin A acts as a potent inhibitor of trehalase, an important enzyme in carbohydrate storage and ultilisation in fungi.

DTXSID4058073CHEMBL1923413、CHEMBL520780CHEBI:29703定義ChEBI: A member of the class of validamycins that is (1R,2S,3S,4S,6R)-4-amino-6-(hydroxymethyl)cyclohexane-1,2,3-triol in which the hydroxy group at position 1 has been converted to its beta-D-glucoside and in which one of the hydrogens attached to the nitrogen is replaced by a (1R,4R,5R,6S)-4,5,6-trihydroxy-3-(hydroxymethyl)cycloh x-2-en-1-yl group. It is the major validamycin produced by Streptomyces hygroscopicus.
